• TRU-TUNE+™Adaptive Control : Enable adaptive
control using the unique TRU-TUNE+™ adaptive al-
gorithm and optimize even difficult-to-control or dy-
namic processes. TRU-TUNE+™ monitors the process
variable and adjusts the control parameters automat-
ically to keep your process at set point and optimize for
set point and load changes.
• User-Programmable Logic : Customize the control-
ler to run custom closed-loop control algorithms or pro-
cesses. All closed-loop control parameters and system
I/O are available for user programs. Program and
closed-loop control variables can be shared or indepen-
dent. Use LogicPro software to write, monitor and de-
bug logic programs.
• Direct Connection of Mixed Thermocouple Sen-
sors:
Connect most thermocouples to the controller
with no hardware modifications. Thermocouple inputs
feature reference junction compensation, lineariza-
tion, offset calibration to correct for sensor inaccura-
cies, detection of open, shorted or reversed
thermocouples, and a choice of Fahrenheit or Celsius
display.
• Accepts Resistive Temperature Detectors
(RTDs):
Use three-wire, 100 Ω , platinum, 0.00385-
curve sensors. Special inputs must be installed.
• Automatic Scaling for Process Analog Inputs:
The CPC400 series automatically scales process in-
puts used with industrial process sensors. Enter two
points, and all input values are automatically scaled.
Special inputs must be installed.
• Dual Outputs: The CPC400 series includes both heat
and cool control outputs for each loop. Independent
control parameters are provided for each output.
• Independently Selectable Control and Output
Modes:
Set each control output to on/off, time propor-
tioning, Serial DAC (digital-to-analog converter) or
distributed zero crossing mode. Set up to two outputs
per loop for on/off, P, PI or PID control with reverse or
direct action.
• Boost Output Function: Set digital outputs to func-
tion as boost on/off control in association with any
alarm.
• Flexible Alarms: Independently set high and low
alarms and high and low deviation alarms for each
loop. Alarms can activate a digital output by them-
selves, or they can be grouped with other alarms to ac-
tivate an output.
• Global Alarm Output: Any alarm event activates
the global alarm output.
• CPU Watchdog: The CPU watchdog timer output no-
tifies you of system failure.
